IMPROVEMENT m WATER-ELEVATORS.

' Specification forming part of Letters Patent N0. 137,754, dated April15,1873; application filed September 7, 1872.

To all whom it may concern:

Be it known that I, JARED A. AYRES, Of Mystic River, in the county ofNew London and, State of Connecticut, have invented certain newanduseful Improvements in Methods of Raising Water;- and I do herebydeclare means of compressed air applied either directly from an air-pumpor from an air-reservoir, into which the air has been previously forced.It also consists in the peculiar mechanical devices, hereinafterdescribed, by which this is efl'ected. The object of my invention is tocarry water, under pressure, to any part of a building or to any desiredheight from a well, river, or other source of supply without previouspumping to a reservoir at a higher level to give the required head orpressure.

The essential parts of my apparatus are an air-pump, an air-reservoir,an oscillating pair of chambers from which the water is expelled by thepressure of the condensed air, and the necessary connecting anddistributing pipes.

In the accompanying drawing on three sheets, Figure 1 is a top view ofmy improved apparatus, with the water-chambers as they would be whenchanging position after one is emptied. Fig. 2 is a front view of theapparatus, showing the air-reservoir and pump in full lines, and thewaterchambers behind in dotted lines. Fig. 3 is a section through thewater-chambers in the position they assume uile the water is beingdischarged or ready ."i be discharged on turning a delivery-cock.

A isan air-pump of ordinary construction, operated by hand or anysuitable power. B is an air-reservoir, into which the air is compressedby the pump A. O is a well or cistern containing water, in which thechambers forming the water-pump are submerged. D and E are .theoscillating water-chambers suspended in a frame turning about the center0. These chambers have in their bottoms the valves (1 and e openingupward. F is a pipe leading from the air-pump to the reservoir forcompressed air. G is a pipe from the air-res-.

ervoir to the pumping apparatus for raising.

the water. It divides into two pipes, H and I, leading to the tops ofthe chambers E and D. J and K are pipes, by whichthe air passes out ofthe chambers after it has done its work. L and M are ascendingwater-pipes, which carry the water forced out of the chambers to anydesired point. After leaving th e chambers they unite in one main pipe,N. O, P, and Q are stop-cocks in their respective pipes,.the use ofwhich will be hereinafter explained. It

is a delivery-cock in the pipe N. a and b are cheek-valves in the pipeN. S and T are bars on the frame that supports the oscillating chambers.They are so placed that the rod Uupon the oscillating frame is broughtagainst them as it swings to one side or the other. The pipes H I J Kpass between these bars and the rod U, in the manner shown in thedrawing, so that when the chamber D is uppermost, as shown in Fig. 3,the pipes I and K are squeezed and closed, and when the chamber E isuppermost the pipes 11 and J would be closed, leaving I and K open. Thisform of valve is shown to illustrate the invention, but any form ofvalves operated by the swinging of the chambers would accomplish I thesame result. V and W are tilting levers held in place by the spiralsprings X and Y. They serve to catch and hold the descendingwater-chamber until a certain force overcomes the pressure of the springand allows thechamher to escape and rise.

The operation of my invention is as follows: Air is pumped into thereservoir 18 until it acquires the requisite pressure. This is done byclosing the cock P and leaving 0 and Q open while the pump A is working.When the reservoir is charged the cooks O and Q should be closed, unlessit is desired to immediately use the compressed air, when]? and Q areleft open. When the water-chambers are in the position shown in Fig. 3,and submerged before any water is drawn, they are both full of water. Ifthe delivery-cock R is now opened, the pressure of the air from thereservoir B acts through the pipe H upon the water in E and forces itout through the pipe M to the delivery-cock. ater can thus be drawn fromthis PATENT OFFIC chamber until nearly exhausted, when, it being nearlyfilled with air, the weight of the full chamber D preponderatcs, and, bycompressing the spring X, allows E to escape and rise; D descends, andis caught by the latch W. The pipe K is opened, which allows the air toescape-from the chamber E, which immediately fills with water throughthe valve 6. The pipe I is opened, which admits the pressure to thesurface of the water in D.' The pipe J is closed, which prevents theescape of air from D, and the pipe H is closed, which cuts off thepressure from E. The apparatus is now in position to use the water fromthe chamber D in the same manner as that from E was forced through thedelivery-pipe. The two chambers thus alternately discharge theircontents through the delivery-pipe N so long as the cock is kept open..When it is closed the operation of the pump stops.

It is sometimes desirable not to use thesupply of compressed air in thereservoir B, but to obtain the requisite power directly from theair-pump. In this case the cock Q is allowed to remain closed and O andI? open, when the pressure from the pump A acts directly upon the waterin the chambers E and D so long as the pump is worked. "Theconnecting-pipes between the several parts of the apparatus need not beexactly as arranged in the drawing so long as they admit of the samecommunications between the parts that are herein described. It isgenerally more convenient to place the air-reservoir at a point distantfrom the water. It may be placed in any convenient position and beconnected with the other parts of the apparatus by suitable pipes. Itmay also be large or small, according to the amount of water to beraised and the time it is required to act without refilling.

Claims.

{voirfor compressed air, and an automatic continuously-actingwater-pump, constructed substantially in the manner herein described.

' 3. The combination of a reservoir of compressed air with an automaticcontinuouslyacting pump and delivery-cocks, by the arrangement of whichthe action of the pump is controlled, as herein described.

4. A. self-acting pumping mechanismpc'onstructed substantially in themanner described, in combination with a delivery-cock, so that itsaction can be started by opening the delivery-cock and stopped byclosing it through the intervention of the inclosed water, substantiallyas herein specified.

5. The arrangement of the water-chambers with their supply and waste-airpipes in such a manner that the motion of the water-chambers opens andcloses the communication through the pipes, substantiallyfin the man-,

ner specified.

6. The latch V with its yielding spring X, or its equivalent, to allow acertain force to detach the chamber E, substantially as described. v J.A. AYRES.
